&lt;!-- TWO STEPS TO INSTALL SPACE TRIP:

  1.  Add the onLoad event handler into the BODY tag
  2.  Copy the coding into the BODY of your HTML document  --&gt;

&lt;!-- STEP ONE: Insert the onLoad event handler into your BODY tag  --&gt;

&lt;BODY BGCOLOR="#000000" onLoad="fly()"&gt;

&lt;!-- STEP TWO: Paste this code into the BODY of your HTML document  --&gt;
